Switch PIC16F877 ON/OFF

[koossa]

Hi Melanie

Thank you for your reply!

You've shot yourself in the foot with the way you've designed your circuit.

What is a better way to design it, I can still make changes to my design?

Probably i don't understand the whole thing as it's suppose but here's what i suggest.

remove the diode and blah blah. Use only your keyboard.

You just want to monitor the ON switch right???

This switch is attach between RB.3 and RB.4 right???

NOW what about...

' define and blah blah 
'
'
HIGH MAXPIN
LOW PORTB.3
OPTION_REG.7=0 'enable internal Pull-UP
While PORTB.4 : WEND ' wait untill ON button is pressed
LOW MAXPIN

This should work

Hi Steve,

I'm not sure if I understand you correctly.

The MAXPIN is HIGH by Default, which keep the Power to the PIC Off.
If I press the ON Button, it pulls the MAXPIN to LOW and the circuit will switch on.
The First Line of your Code, "HIGH MAXPIN" Would then switch the Power to the PIC Off?
